What is Pluck, in regards to space?

[Danielle]

I have to do a research project for Astronomy, and my topic is Pluck. I can't find anything about what it is. The closest I got was that it's a galaxy, but I have no clue if that's right or not, because I couldn't find anything else. Please Please Help! Thank you!

You must mean Puck.

It's a moon of Uranus.
